This is a fix to eliminate the 65590, 65591, 65592 false misfire code problem on all Polaris RZR, General, Ranger, 900 and 1000 models. This is for machines with the stock Polaris factory programming. This fix can not be performed on ECU's that have been tuned by another tuning shop.

Here at Gilomen Innovations we have spent countless hours learning the ECU logic on these Polaris machines in order to fix problems like this.

If you your machine keeps throwing any of the codes 65590, 65591, or 65592 then this is the fix for you. Many people have gone around and around with their Polaris dealership trying to find a fix for this issue when the dealership can not provide a real fix. They will try and sell you a new belt and some spark plugs in order to prevent these codes from coming on when several miles down the road the codes just come back and most people realize they just wasted several hundred dollars at the dealership.
